Indentation Deformation and Fracture of Densified Silicate Glass
The Vickers hardness and Vickers indentation morphology were investigated on a predensified sodium trisilicate glass and the results were compared with those of undensified glass. By densification, the hardness increased, and well developed radial cracks appeared from four corners of the Vickers indentation, while surface flaws became less noticeable.
